Volfenhag ZX-4722

I owned a pair of these 12" subs for approximately 3 weeks before they blew out. It was not even confirmed if it was because of the particular wiring configuration but they were wired according to included instruction and still ended up blowing out along with the outputs on my 4 year old Alphine 1200 W Mono block amp.. I don't know if I will end up purchasing these again. maybe, maybe not.. the color and price would be about the only reason I would buy them again.. I don't recommend though if you want a durable pair of subs. durable does mean more $$$ though..

I got one used for $20 and was very happy until I stepped into a kicker CVR. But i spent 2 and a half times as much on the kicker cvr ($50) but it makes good noise and beats but it is definitely power hungry.

The magnet structure is SO heavy it's ridiculous!

I blew mine with 600 watts RMS and now my friend uses the magnet out of it to stick things to i beams and cars.

The rear vent screen does have a tendency to fly off so you have to super glue it then problem solved.

Great sounding subs. Pound hard and really clean. Have 2 hooked to rockford fosgate 2400 in series at 4 ohms. Subs are power hungry, in-box flier says 350 watt rms but seems closer to 600. Only owned for 1 month but very impressive subs.

Well I have the ZX-4812 sub from Volfenhag, hooked up to a Volfenhag 2,000 watt amp, and man, loudest stand-alone 12 I've ever heard...I was at my friend's house, and I turned on my H.U. to..VOLUME 2! and his sister, which was approx. a 100 yards away, literally, said it was shaking her house...so ya, if this model is anything like mine...then get it :) It's def a head-turner if you have it hooked up properly.

Great subs to have, especially for the price.
